30 Video: Atomic Laws

Law of Conservation of Mass

The Law of Conservation of Mass states that matter is not created or destroyed—it only changes form.

Law of Definite Proportions

The Law of Definite Proportions states that a compound will always contain the same ratio (of either atoms or mass) of the same elements.

Law of Multiple Proportions

If two elements combine in a different ratio, the result is a different compound. In other words, the same compound will always form from the same elements in the same ratio.
